Specification of Letters Patent.

Application filed August 19, 1920. Serial No. 404,531.

' T all from it may concern.

Be it known that I, CHARLES E. EPWORTH, a citizen of the United States, and residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Gas-Heaters, of which the following is a specification,

such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to gas heaters and particularly to heaters of this class designed to be mounted within and beneaththe floor of a room or compartment to be heated and preferably mounted within the cellar of a building but which may be located in any desired compartment, and the object of this invention is to provide a heater of the class specified with improved means for supplying and circulating fresh airto the burner or burners of the heater; a further object being to providemeans for automatically disposing of debris or other matter which may pass down through thegrating of the heater; a still further object being to provide means for circulating air around the heater within the compartment below the floor of the room which is to be heated and with these and other objects in view the invention consists in a heater of the class specified which is simple in construction and operation and efficient in use, and which is constructed and operated as hereinafter described and claimed.

I-Ieretofore it hasbeen customary to place heaters of the class under consideration-on the floor of a room or compartment to be heated, and these heaters are in extensive use in the home'as well as in stores and other business places and particularly the retail chain stores, but in thisuse of heaters it has been found by reason of the location objections-eliminated as well as a great saving in the space of the room or compartmentto be heated, efiected. I

The invention described and claimed herein is an improvement on that shown and described in aprior application filed by'm'e Apr. 8, 1920, Ser. No. 372,142, and is fully which the separate parts of my Improvement are desig nated by suitable reference characters in each of the views, and in which: I

Patented Sept. 1921.

disclosed in the following specification'and accompanying drawings, in l Fig. 4 a partial section on the line l tof Fig.- 3.

In F ig." 1 of the drawings, I have indi-' cated at 5 the fioor of a room or compartment which is to be heated, at 6 the floor I beams and at '7 a part of a door which forms an exit to a building-in which the room to be heated is located.

In practice, the floor 5 is provided with an aperture or opening 8 and my improved,

heater 9 is mounted in connection with and suspended from the floor 5 withinthe opening 8 thereof. The heater'comprises a top grate plate 10 having a plurality of apertures 11 and a downwardly directed flange 12. Secured to the flange 12 is a main'heater casing 13 preferably composed of sheet metal and which is oblong and rectangular in form, in 'the' construction shown, and comprises a front'wall 14, a back wall 15 and side walls16. A bottom 17 ishinged ,to the back'wall 1 5 as shown at 18' and provided] centrally of the front "edge portion thereof with a hinge member 19, one part ofwhich 'extends upwardly asshown at 20 and isprovided with an aperture through which an apertured lug' 2lsecured to the front walllt is adapted to pass, and this construc-" tion serves to supportthebot-tom 17 or the casing 13 and may be'locked against movement by a lock or other device passed through the aperture 22 in the lug 21. The

thereof.

lVIounted within 'an'd spaced from the ibottom. portion' 23 of thefront wall 14 is hinged to the upper p'ortion2t thereof as shown at 25 to permit of the forward and main heater casing 13 is a supplemental casing 26,'which is of the same general form as the casing 13 and the upper end of which is secured to a head member 27. as shown at 28. The head member 27 forms a top or closure for the supplemental casing 26 and the walls thereof converge upwardly as clearly shown in Figs. 1 and 3. The head member 27 is provided about the periphery thereof with a rim portion 29 which is secured to the inner face of the main casing 13 and by means of which the supplemental casing 26 is suspended within said main casing and adjacent to the rim portion 29. The head member 27 is provided with a plurality of apertures 30, and the top portion of the casing 23 is provided with a'plurality of apertures 31.

The front wall 32 of the supplemental k casing 26 is provided with an aperture or clearly shown in Fig. 1 of the drawing, and

the bottom portion 23 is provided with a small central aperture 37 through which the burner of the heater may be seen without raising the bottom portion 23.

The supplemental casing 26 is provided above the bottom 39 between which and the bottom 38 is an air box or chamber 40 centrally of which is arranged an upwardly inclined deflector plate 41 having side walls 42.

The back wall of the main and supple mental casings 13 and 26 is provided centrally of the bottom portion thereof with an aperture 43 adapted to receive an air pipe 44. The pipe 44 may be of any desired length and formation and is connected with a vertically arranged pipe 45 which passes upwardly through an aperture 46 in the floor 5 in the room or compartment to be heated, or the floor of any other room of the building which has a door, such as indicated at 7, which opens to the street or which forms an exit to such building, and secured to the top of the pipe 45 and to the floor is a grate plate 47 The supplemental bottom 39is provided centrally thereof with a plurality of apertures 48 through which air from the airbox 40 is adapted to pass to the burner 49 of the heater. The burner 49 comprises a tube provided with a plurality of burner tips 50 which are mounted therein and spaced longitudinally thereof and said burner tube is'located centrally and longitudinally of the bottom portion of the supplemental casing 26 above the supplemental bottom 39 thereof. A fuel supply pipe 51 is placed in communication with the burner 49 through a pipe 52 and a suitable valve device 53 is mounted between the pipes 51 and 52 and is adapted to control the supply of fuel to the burner. The valve device 53 is secured to the supplemental casing 26 and passes through the downwardly directed eX- tension 35 of the reinforcing strip 34 as clearly shown in Figs. 1 and 2 of the draw- IIIOS.

The baflling device 54 is suspended within and independent of the walls of the supplemental casing 26, said device being suspended from rods or bolts 55 secured to the head member 27 and which pass through the baffling device 54. The baffling device comprises an outer casing 56 having an inwardly directed top wall 57 provided centrally thereof with an elongated opening 58 which extends approximately the full length there-v of. Mounted within the casing 56 is a central baffling plate 59 which is of less transverse width than the inside dimensions of the casing 56 thus forming passages 60 at the opposite sides of said plate. The plate 59 is provided centrally with a downwardly directed longitudinal rib 61 and with an upwardly directed longitudinal rib 62 at the opposite sides of which are fins or ribs 63. The baflling device is also provided with a bottom plate 64 having a central elongated aperture 65, and the plates 59 and 64 are held within the casing 56'by the rods or bolts 55, as clearly illustrated in Fig. 1 of the drawing.

In the use of my improved heater it will be seen that fresh air may pass downwardly through the grate 47 and pipe 45 at each time that the door 7v is opened, and said air will pass intothe air box or chamber 40 through the pipe 44 and be deflected to the opposite sides of the deflector 41, as indicated by the arrow as in Fig. 2, and then passed forwardly around the side walls 42 of said deflector and upwardly through the apertures 48 to the burner 49, and the heated air from the burner will pass upwardly through the baffling device 54 and out through the apertures 31 in the top of the supplemental casing and then upwardly through the apertures 30 in the head member 27 and out through the apertures 11 in the grate 10 and thus into the room or compartment which is to be heated. It will also be apparent that some of the heated air will pass around the periphery of the baffling device 54 and thus tures 31.

The construction of the heater will'be such that the transverse dimensions thereof will be less than the distance between the faces of the floor beams 6 to provide'air chambers 66 at the opposite sides of the heater so that air may pass upwardly around the walls of the heater and out through apertures 67 arranged around the edge portion of the grate 10. This circulation of air will render the heater fireproof in that it will out through the aperprevent any possibility of the -igniting ofthe floor beams 6.

In the operation of igniting the burner 49 on the hinges 25 and the Valve device 53 may then be opened and the burner ignited through the aperture 33 in the supplemental casing 26. After which the parts 17 20 and 23 may bereturned to their normal position. The above operation of igniting the burner will automatically clear out the heater of any debris that may have collected in the bottom thereof which debris will pass downwardly over the head member 27 by reason of this formation through the apertures 30 and thus downwardly into the bottom of the main casing 13, and in this way it will be apparent that the heater is kept clean at all times and such result accomplished automatically by the dropping of the bottom 17 in the manipulation of the apparatus.

It will be apparent that I am not necessarily limited to any specific use of my improved heater nor to the detail of construction herein shown and described, and various changes therein and modifications thereof may be made, within the scope of the appended claims, without departing from the spirit of my invention or sacrificing its advantages.
